Applications: • Seismic Surveys • Naval Exercises • Pile Driving “Force Multiplier” Examples MBES Results – Mississippi Oyster Bed Test

• “Force Multiplier” program in parallel with DEA hydrographic survey vessel • Excellent feedback from NOAA, US Army Corps of Engineers, others. • EdgeTech 6205 MPE & Sidescan Narrow Beam Survey – Bering Sea • “Force Multiplier” program in parallel with Terrasond hydrographic survey vessel • SMBB200-3. 200kHz, 3 degrees. Used with an Odom CV100. “eChart” software was used to control the singlebeam and Hypack 2014 was used to collect all the data. Post-processed kinematic (PPK rather than RTK) GPS positioning with a Trimble system. Hemisphere V113 for heading, heave, pitch, and roll.

USBL Field Data Comparison – CW6 vs. Stinger Mounted Gyro USBL Data

• Intentional offset of data for display purposes • C-Worker 6 data is quiet, indicates ROV stoppages at pipe joints • Over 100m Horizontal and vertical offsets of stinger USBL from GPS antenna; less than 2m offsets for C-Worker 6. • Data recorded during pipe lay operations in the GoM, 2014. • A dramatic increase in signal to noise ratio with the C-Worker 6 USBL
